Diagnosis. Recognized by the following combination of characters: relatively large, male 3.8–3.9, female 4.0; clavus with small transverse dirty whitish fascia just behind apex of scutellum, located on inner margin and not reaching claval suture; corium uniformly brown, without whitish spots or pruinosity; apical half of hind femur and basal three-fourths of hind tibia with reddish tinge ( Fig. 1); pronotal collar narrow, slightly shorter than width of antennal segment II at base ( Fig. 2 ); genital capsule without ventral spine or process ( Figs. 16, 17 , compare with Fig. 4 in Yasunaga 2012); vesica long, J-shaped, with comparatively short apical blade and characteristically dentate expanded portion of lateral strap near secondary gonopore ( Figs. 11, 13, 14 ); left paramere with thin and almost straight apical process ( Fig. 10 ); phallotheca with distinct apical tooth ( Fig. 8 ); sclerotized rings strongly converging apically, large, occupying almost entire sides of dorsal labiate plate ( Fig. 18 ).

Six currently known Cleotomirs spp. clearly differ from the new species in having two transverse bands on their hemelytron, that is, whitish fascia behind the apex of the scutellum and a pruinose area on corial apex. These bands are somewhat poorly expressed in C. chinensis and C. borneoensis ; however, the former species can be easily recognized by its small size and its swollen, cylindrical antennal segment II (see Fig. 246 in Schuh 1984); the latter species differs from C. josifovi in its smaller size, relatively large eyes (Fig. 247 in Schuh 1984), and strongly elevated and swollen posterior lobe of pronotum (Fig. 248 in Schuh 1984). All congeners further differ from C. josifovi in the structure of the male genitalia, with a remarkably short body of the vesica with a contrastingly large secondary gonopore and short ( C. bicolor , C. borneoensis , and C. miyamotoi ), undeveloped ( C. chinensis ), or distinctly elongate ( C. schneirlai and C. yamadakazi ) apical blade. Male genitalia of the new species are somewhat similar to those of C. yamadakazi in the structure of both parameres and apically toothed phallotheca, but clearly differ in the short apical blade of the vesica, the subapical secondary gonopore with adjacent serration, and the genital segment without ventral spine.

Description. Male: COLORATION ( Fig. 1): Dorsum chestnut brown to pale dirty brown; head uniformly golden brown, mandibular and maxillary plates with faint reddish edging; eyes dark reddish; antennal segment I entirely, segment II in basal half pale yellow, apex of segment II, segments III and IV somewhat darker, pale brown; labium uniformly chestnut brown; pronotum and scutellum chestnut brown, disc of pronotum basally and extreme apex of scutellum somewhat paler; thoracic pleura chestnut brown, with pale edging of pro- meso- and metapleura; scent gland evaporatory area whitish, with slightly darkened apex of perithreme; all coxae and basal halves of all femora pale yellow, apices of fore and middle femora slightly, hind femur distinctly darker, pale reddish brown to chestnut brown with reddish tinge; fore and middle tibiae pale yellowish, with distinct reddish tinge in basal half, hind tibia almost entirely pale reddish, with pale yellow apex; tarsi pale yellow; hemelytron almost uniformly brown, with somewhat darker, chestnut brown cuneus, clavus with dirty whitish medial area forming transverse spot just behind apex of scutellum; membrane smoky brown with whitish area at base; abdomen uniformly chestnut brown. SURFACE AND VESTITURE: Head, pronotum and scutellum distinctly shiny, smooth, only anterior part of pronotum just behind pronotal collar and sides of scutellum faintly rugose; hemelytron smooth; middle of clavus, basal half and apex of endocorium matt; cuneus, exocorium, area in distal two-thirds of endocorium, base and apex of clavus shiny. Entire dorsum clothed with mixture of contrastingly long and rather robust, erect to semierect pale simple setae and short, recumbent shining woolly setae ( Fig. 5 ); antenna and legs with short semierect pale simple setae; tibial spines pale, thin and rather short, arranged in two rows on inner surface of each tibia. STRUCTURE: Macropterous, non-ant-mimetic, body elongate-oval, 3.2–3.3 times as long as basal width of pronotum; total body length 3.8–3.9, length from apex of clypeus until apex of cuneus 3.2–3.3. Head: Distinctly projecting beyond anterior margin of eyes in dorsal view, width 0.7, length 0.5, 1.2–1.3 times as wide as long in frontal view; vertex weakly convex, with distinct transverse carina along basal margin ( Fig. 2 ), width between eyes 0.3, 1.8–2.0 times as wide as eye in dorsal view; frons flat, sloping; eye occupying almost entire height of head in lateral view; antennal fossa located slightly above ventral margin of eye; antennal segment I short, 0.3; segment II 0.9, gradually increasing in diameter apically, 0.7–0.8 times as long as basal width of pronotum, 1.3–1.4 times as long as width of head; segments III (0.6) and IV (0.4–0.5) rather stout, somewhat wider at middle, spindle-shaped; labium slightly surpassing bases of hind coxae. Thorax: Pronotum trapeziform, with distinctly concave lateral margins, basal width 1.2, length along midline 0.7; pronotal collar distinctly delimited, flat, narrow, slightly shorter than width of antennal segment II at base ( Fig. 2 ); calli flat, almost not demarcated; mesoscutum not exposed, entirely covered with pronotum; aperture of mesopleural apodeme conspicuously large, oval, mesopleural suture not developed; scent gland evaporatory area broadly triangular, with broadly rounded angles and distinctly elevated peritreme ( Figs. 3, 4 ). Hemelytron: Broadest just anterior to cuneal fracture, with costal margin weakly concave in basal twothirds; cuneal fracture not incised, short and almost perpendicular to costal margin; cuneus wide at base, broadly triangular; medial fracture of corium reaching apical two-thirds of corium; larger cell of membrane apically angulate. Legs: Femora long and slender, hind femur somewhat swollen apically, tibia rather stout, length of hind tibia 1.8; tarsus relatively short, segment III 1.5 times as long as segment II, equal to length of segments I and II combined; claw ( Figs. 6, 7 ) short, curved at midpoint, with small basal tooth; pulvillus attached to claw along entire length and reaching midpoint of claw; parempodia lyre-shaped, apically convergent, weakly flattened, with somewhat spatulate apices. GENITALIA: Genital segment: Moderately sized, about 0.3 length of abdomen, trapeziform, of nearly equal length and width at base, without additional processes or distinctive ornamentation ( Figs. 15, 16 ). Parameres: Right paramere lanceolate, of typical phyline shape, with long and straight apical process ( Fig. 9 ); left paramere ( Fig. 10 ) with triangular, strongly tapering sensory lobe and straight, rather thin apical process. Apex of phallotheca: Broadly rounded, with conspicuous subapical tooth ( Fig. 8 ). Vesi ca: J-shaped, comparatively robust, terminating with long and gradually tapering claw-shaped blade; secondary gonopore subapical, oval, with well-developed sculpture, partly covered with expanded and upturned portion of lateral strap with characteristically dentate margin ( Figs. 11 – 14 ).

Female: COLORATION, SURFACE, VESTITURE, AND STRUCTURE: As in male, although slightly larger, 3.4 times as long as basal width of pronotum, total body length 4.0, length from apex of clypeus till apex of cuneus 3.4. Head: Somewhat longer than in male, width 0.7, length 0.6–0.7; vertex width between eyes 0.4, 2.0–2.2 times as wide as eye in dorsal view; lengths of antennal segments equal to those of male, segment II 0.8–0.9 times as long as basal width of pronotum, 1.4 times as long as width of head. GENITALIA: Dorsal labiate plate with large distinctly elongate and posteriorly converging sclerotized rings, ( Fig. 18 ); vestibulum strongly sclerotized, comparatively wide and short, C-shaped ( Fig. 17 ); vulva with two almost straight sclerites at sides; posterior wall with two well sclerotized sclerites fused at midline and dorsally extending into rod-like process.

Etymology. The species is named after its collector, the late Michail Josifov, in recognition of his substantial contributions to our knowledge of heteropteran systematics.

Distribution. This species is known from just two close localities near Pyong Kang, North Korea.

Host. All specimens of this species were sampled from Ulmus sp. ( Ulmaceae ). However, as almost nothing is known about the biology of Cleotomiris spp., we refrain from any conclusions on host specificity.
